The Scottish Pro14 outfit have never qualified past the quarter-final stage of the European competition, and being tasked to win against the reigning English domestic champions and two-time European title-winners makes Glasgow’s aspirations of qualification that much more difficult.
However, Rennie is adamant his side will put up a fight as they go in search of a final four placing.
“We’re not trying to claim an underdog status because we’re going to go down there and throw everything at it,” he told The Scrum Magazine.
“We know where our opportunities are and we know where their threats are as well. We’re going to have to be really resilient without the ball and really clinical with it but if we can muster that for a big chunk of 80 minutes, we’ve got a chance.
“We’re certainly not satisfied with just being part of that post-pool place. We’re determined to create a bit of history and get into the semis.”
The decision to bench 51-test Scottish lock Johnny Gray a point of interest from a selection perspective by the 55-year-old coach, but he is confident in the ability of starting second rower Scott Cummings, who has been in good form for Glasgow.
“Scott’s done an excellent job calling our line out, he’s a really good athlete and he runs good lines. He’s played really well recently and it’s right to reward that.”
The return of star Scotland fullback Stuart Hogg will have a big impact on the Warriors after a long injury lay-off, while young first-five Adam Hastings is another player Rennie hopes will have a significant influence on the clash in London.
“Obviously he’s [Hogg] lethal with the ball in hand but the quality of his kicking game is really important for us too,” Rennie said.
“Adam’s been in really good form for Scotland recently. He’s got a bit of x-factor about him, and a good skill set so we’re confident he’ll steel up for what’s an important encounter.”
